Part of the hydrotesting procedure includes sending cylinder-shaped “pigs” through the pipe to perform a variety of functions such as cleaning, removing moisture, gauging for dents or ice accumulations, and for filling the pipe with water during the test. [PC3101-15, # on slide], 1977-04

Another activity that took place during the period was the testing of heat pipes. Almost 120,000 radiator-topped thermal devices, called heat pipes, are installed in vertical support members for much of the above ground portion of the pipeline. The heat pipes dissipate heat from the ground to insure pipeline support structures have a solid, permanently frozen base., 1977-04

An infrared sensitive lens mounted outside the helicopter “takes the temperature” of each heat pipe and transmits the reading to a video camera. The information is displayed on a video screen. The brighter the images appearing on the screen, the more heat is being radiated from the heat pipe. A mal-functioning heat pipe appears as a dark image., 1977-04
